While Installing my pc I have set my memory ratings on the BIOS v1.5 to 1:2.66 to have him understand I have 1066Mhz memory blocks. When I additionally install Windows Vista without any driver, my computer works fine. When I install the Motherboard drivers (chipset etc.) with the CD, all still works great. After that I installed my videocard drivers and from then on I receive an AMDLLD64.sys error when windows is started (when it starts showing the desktop it restarts) by deleting the AMDLLD64.sys file in safe mode I am able to get into Windows Vista again and remove the AMD videocard drivers. After this I updated the whole system, newest drivers from MSI, I read about AMD Power Management Tool which updated and replaced the AMDLLD64.sys file and I downloaded the newest AMD ATI videocard drivers. I installed it all and the same thing happened, a blue screen.

This is one of the joys of putting together your own computer. I've had this problem too. there's a ton of upgrades to different hardware you could try, but eventually I took my system back and went with a few hardware pieces that were more compatible with eachother.
